Figure 1From: Creation of a novel peptide with enhanced nuclear localization in prostate and pancreatic cancer cell linesGlu peptide or TAT was an inefficient CPP for PNA uptake in DU-145 cells. DU-145 cells were incubated with 1000 nM FITC-PNA-EEE or FITC-PNA-TAT; at the indicated times cells were harvested and analyzed by flow cytometry for FITC fluorescence.Back to article page
